Specification of Letters Patent.

Patented May 17, 1910.

Application filed September 29, 1909. Serial No. 520,114.

To all whom it may concern:

Be it known that I, GEORGE T. MoLnon, a citizen of the United States,residing at Dedham, in the count-y of Norfolk and State ofMassachusetts, have invented an Improvement in Machines for Cutting andSlitting Insole-Reinforcing Strips, of which the following description,in connection with the accompanying drawings, is a specification, likecharacters on the drawings representing like parts.

The invention to be hereinafter described relates to cutting andslitting devices for insole linings.

As well known by those skilled in the art, it is usual to reinforceinsoles of boots and shoes by means of a piece of fabric or canvas whichmay be cemented thereto and its edge portions tucked into the channelformed by the usual upturned channel lip. As pointed out in-anapplication filed April 15, 1909, Serial No. i90,160, the dimensions ofthe fabric or canvas reinforce have been such as to practically cover.the entire surface of the insole, although the essential function of thefabric is to reinforce that portion of the insole designed to receivethe fastening means which unite the insole to other portions of the shoestructure, any projecting edge portion of the fabric being cut away.Said application also described an invention, and claimed it broadly,whereby the waste incident to theold manner of reinforcing insoles wasavoided, the characteristics of which invention were embodied in areinforcing strip made narrower than the width of the insole and slittedso that the portions adjacent to or on opposite sides of the slit mightbe separated or spread so as to reinforce that part of the insoleprimarily intended to be strengthened. The present inline 3-3, Fig. 2;Fig. 4 is a front detail view of the collector for assembling a pluralnumber of strips in proper relative position for presentation to thecutting table; and Fig. 5 is a plan view of a fabric or canvasreinforcing strip after it has been produced by the present invention.

The fabric or canvas from which the reinforcing pieces are to be cut isor may be preferably of uniform or standard width and less than that ofthe insoles which are to be reinforced. Long strips of such material arefirst coated on one side with an adhesive or cement and after dryingsufficiently are wound on suitable reels or spools.

A series of reels or spools 2, Fig. 1, each containing a roll of thereinforcing fabric or canvas 3, are suitably supported in a frame 1,said frame, in the present form of the invention, being indicated asangular in shape, though, of course, any suitable frame containing anysuitable number of rolls of the fabric or canvas strip may be employed.

Disposed in suitable relation to the sup porting frame 1. is acollection frame 4, Fig. 1, provided with a series of guide rolls 5 overor between which the several strips of fabric or canvas pass, asindicated in Fig. l, to a collector 6. The collector 6 is indicated indetail in Fig. 4 and preferably comprises a standard 7 rising from abase piece 8 which may be secured by a lug 9 and suitable boltconnections passing therethrough to the collection frame 4:.

Projecting from the standard 7 is a stud shaft 10 at the top thereof, onwhich is mounted a guide roller 11, said shaft 10 being preferablyconnected to the standard 7 by means of a thumb screw 12, whereby it maybe readily detached from the standard 7 for introduction of the stripsof fabric or canvas, as indicated in Fig. 1, the outer end of the studshaft 10 being preferably provided with a pin 13 or other suitable meansfor retaining the guide roller 11 thereon. Secured to the standard 7below the stud shaft 10 is another stud shaft 14: which, like the shaft10, has mounted thereon a guide roller 15, the construction being suchthat the several plies of fabric or canvas passing over the guide rolls5 of the collection frame may be passed between the guide rolls 11 and15 and thus collected in proper position for presentation to the cuttingtable.

Projecting laterally fromv the standard 7 below the guide roller 15 is apin 16 to the outer end portion of which is secured the hub 17 havingthe upwardly extending guide arms 18 which, as indicated in Fig. 1,preferably embrace the outer portions of the guide rolls 11 and 15. Byadjusting the hub 17 on: its supporting stud 16, the arms 18 and hub 17may properly guide the assembled strips of fabric or canvas into properassembled relation for presentation to the cutting table, as will bereadily understood.

The cutting table, one form of which is indicated in Fig. 2, comprises abase portion 19' which may be suitably supported ona bench or othersustaining means and is preferably provided with a trough or guide way20 formed by longitudinally extending side members 21, Fig. 2.

Spanning the guide trough 20 is a retainer Fig; 2', preferably securedby screws 23 or otherwise to the side members 21, said retainer having aforwardly projecting prong or finger 24 adapted to engage with the topof the assembled strips of fabric or canvas which are passed beneath tothereby maintain them in proper place and prevent the ends of theseveral pieces of fabric or strips retreating from the trough 20 afterthe operator has severed the reinforcing sole portions, such as- S, Fig.5.

At the end of the trough 20 opposite the retainer 22 is a stop 25against which the forward ends of the assembled strips bear when theyare drawn forward into cutting position, a cutaway portion 26 beingprovided near the stop 25, so that the hand of the operator may arrangethe ends of the assembled strips in proper relation with the stop 25'.Hinged or pivota-lly connected to suitable supporting arms 27 at 28,Figs. 2 and 3-, is a clamp or cover plate 29, which, when in operativeposition, as indicated in Figs. 2 and 3, is adapted to overlie and restupon: the assembled strips of canvas or fabric beneath.

In the present embodiment of the invention, the clamp or cover plate29has its rear or severing portion 30 preferably somewhat wider than themain body of the clamp or cover plate, said rear or severing portion 30being provided with transverse slits 31 extending the full width of thetrough or guideway 20, the construction being such that when the clampor cover plate is in position as indicated in Figs. 2 and 3, a knife maybe passed down any one of the slits 31 and sever appropriate lengths ofreinforcing sole pieces from the assembled strips.

Extending longitudinally of the clamp or cover plate 29 to the left ofthe rear or severing portion 30 thereof is a slot 32 also adapted tohave passed ther'ethrough a suit able cutter or knife to form the slit33' inthe forepart portion of the reinforcing strip when applied to theshoe sole, as indicated in Fig. 5. Likewise extending longitudinally ofthe rear or severing portion 30 of the clamp or cover plate is anotherlongitudinal slot 34 permitting the passage of a knife or cutter for theformation of a slit 35 in the reinforcing strips near the heel portionof a shoe sole, as indicated in Fig. 5. Likewise extendinglongitudinally in the trough or guideway 20 of the table is a slot 36corresponding to the slots 32 and 34 to accommodate the point of thecutter or knife.

In order to determine the length of the reinforcing strip correspondingto diiferent sizes of shoe sol'cs, consideration must be taken of thefact that since the reinforcing strip S is to be separated at itsslitted portions more or less, as set forth in application Serial No.490,160 hereinbcfore mentioned, therefore for wide soles greater lengthof canvas reinforcing strip must be provided than for the more narrowsoles and likewise the length of the longitudinal slits 33 and 35 willvary. In order to readily meet this condition, the clamp or cover plate29 is provided with suitable marks on its rear or severing portionindicating the particular location of cut corresponding to a wide and toa narrow solc, as

indicated in Fig. 2'. Mounted onthe rear or severing portion and securedthereto by asuitable set screw 37 is a gage edge 38 having a stem 39 bywhich said gage edge may be adjusted to the particular number indicatingthe length of reinforcing strip either in case of wide or narrow soles.Similarly, the longitudinal slot 32 is provided with a series of sizemarks, one for wide and the other for narrow shoe soles, and a gage 40secured to the 01311111101 cover plate 29 by a suitable clamp screw 41may be moved to proper position in accordance withthe character of solobeing treated.

hen the cover or clamp plate 25) is turned down upon the assembledstrips of fabric or canvas, it is desirable that it be held in thisposition while the operator passes his knife transversely and thenl'ongitudinall-y of the assembled strips. To this end there is pivotedon suitable supporting brackets 42 a clamping member 43 having a hand.grip portion 44 and bearing in portions 45, which latter are adapted tocontact with and press upon the clamp or cover plate 29, as will beclearly apparent from Figs. 2 and 3, the construction being. such thatthe operator may with one hand pull up ard upon the hand grip 44 of theclamp and with the other hand may pass his knife through the appropriateslots for slitting and severing the as sembled strips.
